HOW TO USE YOUR CHIP-N-VAC
BEFORE STARTING
1. Your Chip-N-Vac engine is shipped without oil or
gasoline. Service the Chip-N-Vac engine with oil and
gas as instructed in the separate engine manual.
2. Inspect the Chip-N-Vac to make sure all covers (rear
door, vinyl boot, elbow, hose adapter, hose and deck
adapter are properly attached.
3. Check tires for proper ination (12 - 14 lbs). Do not
exceed the maximum pressure printed on the side of
the tires.
WARNING: Never ll fuel tank indoors, or
with the engine running, or while the engine
is hot. Do not smoke while lling tank.
HOW TO STOP YOUR CHIP-N-VAC
1. To stop engine, move the throttle control lever to the
OFF position.
2. Disconnect spark plug wire from plug to prevent ac-
cidental starting while equipment is unattended or is
being worked on.
CAUTION: The muffler and adjacent
areas are hot!
HOW TO START YOUR CHIP-N-VAC
OPERATION
1. Check oil and gas in Chip-N-Vac engine.
2. Attach spark plug wire to spark plug.
3. Move choke lever on engine to CHOKE position.
(A warm engine may not require choking.)
4. Move throttle control lever on engine to FAST position.
5. Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope will
pull slightly harder at this point). Let the rope rewind
slowly.
6. Pull rope with a rapid, continuous, full arm stroke.
Keep a rm grip on starter handle. Let rope rewind
slowly. Do not let starter handle snap back against
starter.
7. Repeat instructions in two preceding paragraphs until
engine res. When engine starts, move choke control
gradually to RUN position.
WARNING: Never start or run the
engine without all covers being properly
attached to the blower housing and cart.
CAUTION: Vehicle braking and stability
may be affected with the addition of an
accessory or an attachment. Be aware of
changing conditions on slopes.
1. Begin operation at low speed, adjusting forward speed
to match grass height and/or moisture condition to
prevent clogging.
2. Do not attempt to vacuum up any material other
than vegetation found in a normal yard, such as light
branches, leaves, twigs, etc.
3. To empty cart, shut off tractor engine and set brake.
4. Shut off Chip-N-Vac engine.
5. Remove rear door from cart.
6. Release the latch holding cart down to the tongue by
stepping on the foot pedal latch. See gure 18.
7. Using a rake or suitable tool, pull the grass clippings
and/or leaves out of cart.
WARNING: Should your Chip-N-Vac
become clogged, shut off tractor and
Chip-N-Vac engines. Before attempting
to unclog, remove wire from spark plug to
prevent accidental starting.
CAUTION: To avoid possible injury, be
sure that no one is near the cart before
releasing the latch.

13
USING THE CHIPPER CHUTE
1. Material such as stalks or heavy branches up to 2" in
diameter may be fed into the chipper chute as shown
in gure 19.
2. Be sure to wear eye protection and gloves when
feeding material into the chipper chute.
4. For best performance, it is important to keep the
chipper blades sharp. If the composition of the
material being discharged changes (becomes
stringy, etc.) or if the rate of discharge slows down
considerably, it is likely that the chipper blades are dull
and need to be sharpened or replaced. Refer to the
Service and Adjustments section, on page 15.
WARNING: Do not attempt to feed any
material larger than 2" in diameter into the
chipper chute. Personal injury or damage to
the machine could result.
DANGER: Keep hands out of chipper
chute. Rotating blades in impeller housing
can cause serious injury. Use the tamper
plug to help push material down into the
chute.

bearings. Use automotive wheel bearing type grease
or 20 weight oil.
WARNING: Always stop engine and
disconnect spark plug wire before cleaning,
lubricating or before performing any repairs
or maintenance.
ENGINE MAINTENANCE
Always use STA-BIL® 360 Performance in every tank
to prevent ethanol related fuel problems. STA-BIL®
is the only approved fuel stabilizer for use in Agri-Fab
equipment.
Only use high quality detergent oil rated with API service
classication SF or SG. Select the oil's SAE viscosity
grade according to your expected operating temperature.

REMOVING THE IMPELLER
1. To remove an impeller that is frozen on the shaft,
order the Impeller Service Tool (part #42294) that is
listed on the parts ordering page 20.
2. Remove the bolt that holds the impeller on the shaft
and screw the impeller service tool into the hole until
the impeller breaks free.
It is important to prevent gum deposits from forming
in essential fuel system parts such as the carburetor,
fuel lter, fuel hose or tank during storage. Also, alcohol
blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to separation
and formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage.
To avoid engine problems while in storage of 30 days or
longer, ll the fuel tank to the top with fresh fuel treated
with STA-BIL® fuel additive to keep the fuel fresh and
make sure it starts next season. Once fuel is treated, run
engine for 2 minutes to circulate stabilized fuel.
